In the process of engine test,waste engine oil should be recycled to ensure the effective and compliant conduct of test.However,the traditional human way greatly reduced the efficiency of the test.This paper conducts research on the recovery technology of waste engine oil in the laboratory.Firstly,this paper analyzes the problems of traditional recovery by manual means;Then,the design scheme of the mobile waste engine oil recovery trolley is proposed,and the real equipment is made according to the design concept;Finally,the feasibility of the design scheme is verified by benefit analysis through practical application,which improves the efficiency of the laboratory engine test and provides technical reference for the recovery of waste engine oil in laboratories at home and abroad.
